These particular
scenes were filmed in Venice, CA., which is located between Marina
Del Rey and Santa Monica.

In Episode
1 (of season 2), "The Distance", we see Ryan come out of that
"Chino" house and carry the trash out to the curb. He sees some
kids riding their bikes on his old street, and flashes back to a memory
of himself as a youth on the same street.

That house
that he shared with Theresa(a small white home with bars on the
windows) is located at 2342 Frey Avenue (the northeast
corner of Frey & Cloy Ave.), in Venice. This isn't the
pricey, well-known Venice canals area, it's a working class, residential
neighborhood about half a mile east of the canals (just north of Marina
Del Rey).

The street,where he watches the children ride their bikes, is actually Olive Avenue(just west of Cloy Ave.) in Venice, CA., just around
the corner from the house.

Warning:
Remember
that these are private homes. Don't trespass on their property,
knock on their doors, or do anything else that might disturb the residents!

Attention:The day I visited these two parts of Venice
& Lawndale, the neighborhoods seemed harmless enough
(although there really isn't much to see there). But those security
bars on the windows might indicate that a crime problem exists; so if you choose
to visit the areas, exercise reasonable
caution.

A. I didn't
have much to go on for these scenes. Just part of the house number (it
was blurry and looked like it might be 2242, 2342 or 2842), and an out-of-focus
street sign (in the flashback scene with the kids on bikes) that could
have been "Clay Ave", "Chey Ave" or "Choy
Ave."

So I started
Googling various combinations of similar numbers and street names. For
some reason, when I typed in "Clay Avenue", the Google map gave
me Cloy Avenue, which turned out to be the right street.

Comparing the
Google aerial maps with the screenshots, the roofs and trees seemed to
match. Given the address, I could limit it to just two or three streets
in the area. So I drove down to Venice and took a look. It's a small neighborhood,
so it isn't that hard to scout. Once there, that wood fence (which the
kids ride past on their bikes) with the banana trees behind it jumped out
at me, then it wasn't hard to find the matching house right around the
corner.
